旱塬区晒旱地水分运转规律及小麦保墒增产途径研究

A Study on the Dryland Moisture Cycle in the Arid Zone and Moistur-Keeping and Yield-Increasing Measures

本文通过近10年旱塬区晒旱地土壤水分的定点观察,对土壤水分的动态变化、垂直变化、周期变化及与小麦生产的关系进行了研究,明确了旱地小麦的需水量及耗水特点,并提出了适期耕耙、底肥早施、秸秆覆盖、冬季镇压等保蓄水分、促进小麦增产的配套措施.

This paper reported the result of the observations on the soil moisture of the dryland in the arid region on the basis of data obtained from the fixed location,in which dynamic, vertical and periodical changes were studied and the water-needing amount and the particularity of water comsumption were pointed out and the yield-increasing measures by way of the seasonable tillage and harrowing,ealier application of basal dressing, soil-covering by straw and stalks and earth-packing.
